Application: kmail (4.10.5)
KDE Platform Version: 4.10.5 "release 1"
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.16-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

Had selected a number of mbox file folders in a mixedmaildir resource.
RMB -> mark all as read
This operation was shown as finished by the activity display in the lower right corner (opened with the blue up arrow), but some folders were still showing unread emails in the folder list.
I selected one of those folders when kmail crashed immediately after the click.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
